Probably a very simple task… but how do I move an audio track of multiple audio clips to a different audio track?
I'd like to move all clips from A2 to A1. If I select all the clips and then use the red arrow tool to move them, it only moves the clip on which i click?

You should be able to draw a box around all the clips and lift them all at once.

Another way would be to mark an in and out on the section, Ctrl C the section, and then in your source window drop down call up the clipboard contents. This will load what you just copied to the source window. use that as a source and edit it to the audio track you want.
